            <p class="text-lg leading-relaxed text-gray-700 mb-6">
                <strong>AOT 编译</strong>指的是在程序运行之前，将 Java 字节码（即中间代码）直接编译成平台特定的机器代码。这个过程通常发生在应用程序的构建阶段，而不是在运行时。这样，当应用程序运行时，它不需要再通过 JVM 的即时编译器（JIT）将字节码转换为机器码，直接使用已经编译好的机器码。

                    AOT 编译本质上是将编译工作从运行时转移到构建时，通过牺牲一定的灵活性来换取更好的启动性能和更可预测的运行时行为。
